ALBERT HOLMES, OF PEIALUMA, CALIFORNIA.

LIFEV-BOAT.

SPECIFICATION forming part of Letters Patent No. 248,097, dated October11, 1881.

I Application filed Ju1 .5,1se1. (No model.)

To all whom it may concern Be it known that I, ALBERT HOLMEs, a citizenof the United States, and residing at Pet-aluma, in the county of Sonomaand State of California, have invented certain new and usefulImprovements in the Construction of Life-Boats, of which the followingis a specification.

The object of my invention is, filst, to provide a life-boat in whichthe requisite buoyancy is obtained by means of alternating layers orhands of air tight metal tubing and cork; second, to provide a life-boatwhich may be constructed from any ordinary boat by simply attaching toit the airtight metal tubes and the alternatinglayers of cork. Theseobjects I accomplish by means of the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a plan view, Fig. 2 is aside elevation, and Fig. 3 is a cross-section.

Similar letters of reference are used to indicate like parts throughoutthe several views.

To the top of the gun wale I secure, bymeans of bolts, screws, orstrap-irons, the air-tighthollow tube A. This tube is divided intolengths or a, and between these lengths I place the rowlocks b, whichare attached to the gunwale in the ordinary manner.

Upon the inside of the boat-frame, and ashort distance below the topedge thereof, I secure the air-tight metal tubes B B. These tubes extendalong the port and starboard sides, in which position-they are securelyheld by any well-known means.

Upon the outside of the boat, a short distance below the top edgethereof, I attach the air-tight metal tube 0, which encompasses thvessel upon all sides.

Between the tubes A and B, Iplace a band or fillet of cork, D, andbetween the tubesA and O the fillet of cork E, and underneath the tube0, and attached to the side framing of the boat, the fillet of cork F.These alternate layers, bands, or fillets of cork serve the denblepurpose of increasing the buoyancy of the boat, and also of protectingthe metal tubes from injury. I also provide metallic air-tight seats orthwarts c, constructed in the form shown, and which are removable, andin themselves form cfficient life-preservers.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

In a life-boat, the combination and arrangement of the air-tight metaltubes A B- 0, secured upon the inner and the outer sidesof theboat-frame in a horizontal manner, and

alternating with horizontal layers or fillets of cork, D E F, all whenconstructed and arranged substantially in the manner as herein set forthand specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 13th day of June, 1881.

, ALBERT HOLMES. [L.S.]
